desertcart.com: Breathe Naturally - Replacement Filters Compatible with Honeywell Air Purifier HPA300, HPA300 or HRF-R3 Series – Activated Carbon Prefilter – 12" x 17.2", 14" x 17.2" - Easy Replacement - (Pack of 4) : Home & Kitchen

Review: Fit perfect - These fit my Honeywell 300 perfectly. I know these prefilters can be vacuumed but really, only so many times before they are just a dirty filter. The main filters last much longer. These were worth the purchase to have a good clean filter!
Review: Great Substitute - I recently purchased a new freidrich through the wall air conditioner. The replaceable filters from the company are something like $40+ dollars for 3 filters which are approximately 17" x 10". I ordered a 4 pack of these HPA300 filters for about $18. They are 17x14 and the same quality as the friedrich ones. I just trimmed it a little to fit the holder on the ac and they work great. Saved over $20.

### ⭐⭐⭐⭐⭐ The best Carbon Activated Pre Filter replacements for HPA300 I've gotten so far!
*by S***Y on May 10, 2018*

I was hesitant at first, but now I'm so glad I got these. I've purchased other pre-filter replacements before, but I always ended up having to measure and cut them in order to fit perfectly in my Honeywell HPA300 Air Purifier (that, in addition to cleaning up the remains afterwards). With these - there is no cutting. They fit perfectly. All I have to do snug them into the four rectangular pre-filter placement holders and strap it in place, and I'm done. I have a pack of 4, which should last me for quite a while, but once they are finished, this will be the only pre-filter replacement I'll be using.
